PHP

PHP is a widely-used general-purpose scripting language that is
especially suited for web development and can be embedded into HTML. PHP-enabled
web pages are treated just like regular HTML pages and you can create and edit
them the same way you normally create regular HTML pages.

PHP can be used on all major platforms and has support for most
available web servers and a wide range of databases. PHP also has support for
talking to other services using protocols such as LDAP, IMAP, SNMP, NNTP and
POP3.
